CHARLES M. BABCOOK, OF GALESBURG, ILLINOIS, ASSIGNOR OFONE-HALF TO JOHN C. STEVAR'I, OF SAME ILAOE.

-cHEcKRow coRN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 294,839, dated March 11, 1884. Application filed May 9, 1883. (No model.)

"0 all whom, z'- may concern.. Be it known that LCHRLES M. BABcocx, a citizen of the United States, residing at Galesburg, in the county of -Knox and State of 5 Illinois, have invented certain new and useful Improvements in Check-Row Corn-Planters, and I do declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which I it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and igures of reference marked thereon, which form a part of this f specification. My invention relates to improvements in check-row corn-planters; and it consists in the means used for giving the stroke or reciprocating motion to the dropping-slide, as will be hereinafter described and claimed.

In the drawings, Figure lis a plan view of a portion of a corn-planter having my improvements applied thereto. Fig. 2 is a side view of the same, a part of the bar a? being broken away to show the groove therein and the lower arm of the bifurcated vibrating bar; and Fig.

3 is a detail view of the latch-bar,hereinafter described. Fig. 4 shows. a modification, and Fig. 5 is a sectional view on line x x, Fig. 2.

I have shown my operating mechanism mounted on two side bars, c a', connected by an intermediate cross-bar, a2, the said bars a c ai representing a portion of the framing of a corn-planter. In the upper side of the bar d?, extending from the bar a, I from a 5 5 groove, in which the reciprocating bar b is placed and slides. The forward portion of the bar b, or that next to the bar a, is bifurcated to form the upper'arm, d', and the lower arm, b2. The arm b2 is arranged wholly within 44o the groove formed in the bar ai, so that its upper face is flush with the upper face of the said bar, and the said arm is usually made shorter than the arm b', as itonly need extend far enough to provvide a support for the cam c', 45 which will be described. Through the arm b', near its end, I form the elongated opening b3, through which is passed the bolt b4, which, in connection with the staple b5, holds the reciprocating bar within the -groove in the bar at.

For convenience of reference, I call the move- 5o ment of the bar b toward the bar a, its forward 7 and reverse movement the backward motion of same.

On the under side of the arm b and near the main portion of the reciprocating bar b, Iiix the cam c, the cam-surface of which is on its forward side, andis inclined forward from the point where it first receives the action of the rollers, hereinafter described, to the point where such action ceases.

On the upper side of the arm b2 and in ad- .vance of the cam c, I fix the cam c, the camface of which is on its rear side, and is inclined in a manner opposite to the cam c, as shown in Fig. 1, and for the purpose hereinafter de- 6 5 Y scribed.

On the bolt b* and between the arms b bi, I journal the wheel d, which rests on the plate d', and is thereby held sufficiently high to permit its arms, hereinafter described, to move 7o clear of the cam a.

The wheel d is composed of the arms d2 d, crossing each other at right angles, as shown.

In the outer ends of these arm dAZ di, I cut slots dt, which admit the plate iixed on the latchbar, hereinafter described, and the portion of the arms below the slot d* is formed with ashoulder or hook, d", which engages or enters the .recess formed in the latch-bar, as will hereinafter appear.

On the upper side of the arms di, near their outer ends, I secure the pins e, preferably provided with anti-friction rollers, which engage the cam c, and on the under side of and near the outer ends of the arms d3 are secured the S 5 pins e', also preferably provided with antifriction rollers, which engage the cams c in the operation ofthe machine.

The knotted rope f, having buttons or knots f', is passed around pulleys g g', mounted on 90 the bar a, as shown.

The latch-bar 7L is pivoted at one end on the pin h, fixed on the bar a, and extends alongside the pulley g, and its side next the said pulley is rounded at the point h2, forming a bearing, against which the knob or knot on the rope strikes and forces the said latch-bar away, and disengages the arms of the wheel therefrom, In the inner side of the bar 71, near its free or swinging end, I eut the recess or notch It, into which the hool; di on the i arms d d extends and catches, and on the upby the spring i, iixed to the bar a and bearing against the lateh-bar, as shown.

The wheel d and the framing u c u? are arranged in a horizontal position, and the i'eciprocati ng bar I) is connected with the droppingslide j through the pitman j and pivoted or rocking lever f'. The lever j2 is pivoted in suitable manner on the framing, and it is connected pivotally or in other suitable manner to the dropping-slide. The pitman j is pivoted to the bar b, and is provided on its end with a sleeve, j, which slips over the leverj, and may be made fast thereto at any point above its pivotal ccnter by means ofthe setscrew y", so as to regulate the length of the stroke, as will be understood on reference to the drawings.

In the operation of my invention, when the locking-latch and wheel (l are in the position shown in dotted lines, Fig. l, and the hook di on the arms ot' the wheel is engaged in the notch or recess hf", the friction ofthe rope will not revolve the wheel, which will remain stationary until the knot or button j engages against the rounded bearing h2 and forces the lateh-bar back, as shown in full lines, Fig. 1, wh en the arm will be relieved from its connection with the latch-bar, and the buttonf carries the arm a quarter of a revolution ofthe wheel, until the next following arm is engaged bythe latch-bar, when the operation is repeated, the wheel d being revolved intermittingly in the same direction as the machine is moved along the rope. As the wheel is revolved, the cams c c are alternately engaged by the pins on the arms d? d", and the bar b is moved back and forth in its reciprocating motion, which is communicated to the dropping-slide in the manner before described.

In practice, I prefer to secure the pins e e on the wheel d and the cams on the bar b, as shown in Figs. l and 2; but it will be understood that practically the same results would be accomplished were the cams iixed on the wheel d, as shown in Fig. 4, in which case the pins, preferably provided with the rollers, would be secured on the barb, as indicated in dotted lines, Fig. 4. I also preferto bifurcate the bar I), as shown; but it will be understood that the arm b might be dispensed with, and the cam or pins might be fixed on the main port-ion of the bar, as will be understood on reference to the drawings.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, is-

l. In a corn-planter, the combination, with the operating-wheel having slots d* cut in the ends of its bars di, and means whereby said wheel is connected with the dropping meehanisni, and the knotted rope f, ofthe latchbar l1, pivotcd at its rear end, a suitable supportingspring, and the plate 71.*, mounted on the latch and arranged to enter the notches d* in the arms di, said latch-barbeing provided, near its forward end, with the notch if', ar-v ranged to receive and hold the wl1eel.-arms, i and constructed in rear of said notch with the cam or inclined face/1, arranged in position to be engaged bythe rope knots or buttons, whereby the latch is pushed back and the wheel released, all substantially as and for the purposes specified. g 2. The combination, substantially as described, of the operating-wheel provided with pins or rollers secured on respectively the upper and lower sides of its alternate arms, and the reciprocating bar provided with cams secured on said bar, and arranged vertically on opposite and diamet-rically on the same side of the wheel, said cams being inclined in oppo site directions in the plane ot' the wheel, and formed with bearing-surfaces on respectively .g their 'forward and rear edges, said bearingsnrfaces being alternately engaged by the pins or rollers on the wheel-arms, substantially as specified, and for the purposes set forth.

3. The combination, in a corn-planter, of the wheel having its arms provided with pins or rollers e c', and slotted in their outer ends, the pivoted latch-bar l1., supported by spring @and constructed with notch hn and inclined face 71?, the plate h, mounted on said latch and arranged to enter the notches in the wheelarms, the bifurcated bar b, provided on its arms b b2 with cams e c', inclined in opposite directions,and provided on respectively their forward and rear edges with bearing-surfaces arranged to be engaged by the pins or rollers c e', the dropping-slide j, arranged parallel with the bar b, pivoted rodj", secured at its rear end to the dropping-slide,and connected at its opposite end with the har b by means of pitman y, and adjustable sleeve j, and the rope f, all arranged and operatingr substantially as speeified,and for the purposes stated.

In testimony whereof I affix my si gnature in presence of two witnesses.
